Richard, You've only scratched the surface of what "could" be happening (ha). GC or other JVM related stuff could be happening... networking is also a good starting vector - assuming you are right about the SQL and I/O. For example, switches and NICs set to "auto" negotiate can sometimes exhibit this exact behavior if they are resynching for speed or duplex.

We have Fusion-Reactor and can see that there is no heavy traffic on the server. The same query run at a different time, runs just fine. The SQL db queries (as shown by F-R) are running very fast. I/O is also fine at the time this happens as can be seen in the performance monitor. How should we go about finding out the cause of these slow running requests? Thanks!
